Hi All, Before you buy your new mainsheet blocks, consider the M/N 332 mainsheet system from Harken. The attached .pdf file is the Harken data sheet. With the 332 system, you have your choice of 3:1 mechanical advantage for trimming speed in light air or 6:1 power for heavy air. As you can see from the attached drawing, you have 2 mainsheet tails. Pull on either one for 6:1 mechanical advantage. Pull on both together of them for 3:1. I joined the 2 tails together with a long splice that will run thru the blocks. Now, I just have one long loop of a mainsheet that can't get tangled. I have had this mainsheet system on my boat for ~25 years. It's been totally bulletproof. If you have any thoughts re racing your boat, this is the mainsheet system to have. The 6:1 mechanical advantage gives very fine control for mainsheet trimming. It should be reassuring for any weaker members of your crew that they will always be able to control the mainsail. My wife loves it and my sons liked it too when they were kids.
